Perfo processes your photos entirely on your device.
Your photos, the stamps you make, captions, places and dates. Perfo has no account system and no photo upload of any kind.
RevenueCat verifies your one-time purchase and receives an anonymous purchase identifier. The Perfo invite service, used only when you open the invite screen, receives an anonymous install identifier and an invite code so that referral rewards cannot be farmed. Neither receives photos or anything that identifies you.
Deleting a stamp removes its image files immediately. Deleting the app removes everything stored on device.
